Abstract

A method of inhibiting bacterial sialidase comprising administering to a subject an inhibiting effective amount of a compound of formula I: ##STR1## wherein A is CO.sub.2 H, PO.sub.2 H, or SO.sub.2 H; B is N; R.sub.1 and R.sub.2 are H; R.sub.3 and R.sub.4 are, independently, H, OH, NO.sub.2, guanidino, or alkyl or alkenyl of from 1 to 3 carbons where the alkyl or alkenyl is unsubstituted or is substituted, independently, with one or more of OH, NH2, or halide; R.sub.5 is H; and R.sub.6 is COCH.sub.3, or COCI.sub.3 ; or an analog, pharmaceutically acceptable salt, derivative, or mixture thereof. A method of preventing a bacterial or trypanosomal infection using the compounds of formula I. A method of treating a bacterial or trypanosomal infection using the compounds of formula I. A pharmaceutical composition comprising a pharmaceutically acceptable carrier admixed with an inhibiting effective amount of a compound of formula I. A method of making a pharmaceutical composition, comprising admixing a pharmaceutically acceptable carrier with an inhibiting effective amount of a compound of formula I.
